Correct option is B
Given: Leave duration = 7 days. Classes attended = 2 days. Study leave begins = Friday.
Concept: Calendar sequencing and backtracking.
Solution:
Study leave starts on Friday.
She attended classes for the 2 days immediately prior: Wednesday and Thursday.
Before attending those classes, she was on leave for exactly 7 days.
Counting 7 days backwards from Wednesday lands on the Wednesday of the previous week.
Her last day present in class was the day immediately before her leave period started.
The day before Wednesday is Tuesday.
Final Answer: Tuesday
So the correct answer is (b)
